Climbed the Signalkuppe in 1982 and spent 2 nights up at the Margarite Hut, up on the summit. The low atmospheric pressure was apparent when one of my companions opened a container of milk powder, which then erupted like a mini-volcano, plastering him in milk powder from head to foot.

From the Sella hut we went over Il Naso (4100 meter) on to the Monte Rosa trail. In good but windy conditions we traversed the Parrotspitze before reaching the Margherita hut on top Signalkuppe. Coming next morning there was no visibility and we had to cancel Zumsteinspitze and Dufourspitze and instead delicately find our way down the Grenzgletscher to the Monte Rosa hut in poor visibility. (July 27, 2000).

...margherita with the ski, and margherita it was.
After a previouse attempt stopped at lyskjock for the fog, this time after a heavy snowing the day before i reached the hut with other 3 skiers met along the way.
foggy again but then, from lysjock for about 1 hour lasted a great view.

Satuday the weather ws sunny and warm. Wonderfull snow from the top down to Gressoney. But unfortunalty when we left the Gnifetti Hut at 6 AM of Sunday 5th April was snowing and foggy.
In 1:30 we reached the Lysjoch and then.....we wait a while but we were not lucky. The fog turned even thicker.
Then we skied down all the way till gressoney.

Gabi, Sev and I left Mantova Hut at 7am. Wind and sun. We reached summit of Piramide Vincent where we took a short rest and then we continued towards Margherita Hut which we reached at 1pm. All in all a beautiful climb and traverse. We slept in the hut fighting the headache with aspirines and water.
